PJR-010 Use Permit Application Requirements
This information is intended to provide a checklist for applicants to ensure that their applications for a Use Permit are as complete as possible when submitted to Permit Sonoma to facilitate permit processing.
This handout is intended to provide a checklist for applicants to ensure that their applications for a use permit are as complete as possible when submitted to Permit Sonoma to facilitate permit processing. The Sonoma County Code sets forth both uses that are “Permitted Uses” and “Uses Permitted with a Use Permit” within each zoning district. Examples of uses requiring a Use Permit are: wineries, kennels, contractor storage yards, planned developments and mixed use projects. A Use Permit application is required for uses that are typically more intensive than Permitted Uses or may not be the principal purpose for the district. Use Permit applications require an opportunity for public hearing before the Board of Zoning Adjustments. For minor modifications to existing land uses or where the use is minor in nature, the use permit can be approved administratively by planning staff. In these cases, the public hearing may be waived, if no comments are received after notice is provided to neighboring property owners. When a particular use also requires a Zone Change and/or a General Plan Amendment, the public hearing must be held before the Planning Commission and ultimately, the Board of Supervisors.
Use Permits are discretionary in nature and may require site specific studies conducted by qualified professionals related to biotic and cultural resources, water availability, noise, traffic and other issues. A Use Permit can only be approved if found to be consistent with the Sonoma County General Plan, applicable Area or Specific Plans, the Zoning Code and that the use is compatible with the health, safety, and general welfare of the neighborhood. Use permits can take 6 months up to several years to process, depending upon the completeness of the application, the complexity of the project and level of environmental review, and the level of neighborhood controversy. If approved, the use permit will include conditions of approval that must be met prior to vesting the use. Once the conditions of approval have been met, the use permit is considered vested and will run with the land and benefit all subsequent property owners (unless the use is limited term).
After an application is submitted and the project planner in the Project Review Division of the Permit and Resource Management Department (Permit Sonoma) is assigned to the project, the application will be reviewed for completeness to determine if all the required information is provided. Within 30 days of submittal, the applicant will be notified of any additional information required and given a reasonable amount of time to resubmit. An appointment with the project planner is recommended for resubmittal of required application materials. Applicants will generally be given 3 to 6 months to complete an application or it will be deemed withdrawn. Processing timelines begin only when an application is deemed complete. Once the application is deemed complete, a notification is sent to neighboring properties advising them of the proposed use. The application materials are also sent to other divisions of Permit Sonoma, other County departments, and local agencies for review, comment and condition(s). Environmental review in accordance with the California Environmental Quality Act (CEQA) is required unless the proposed project is specifically exempt. Additional information or studies may be required to complete processing of the application. The project planner will prepare an Initial Study that assesses the potential environmental impacts and identifies mitigation measures to reduce potential impacts to a less than significant level that will be added as conditions of approval. If the project planner determines that no significant environmental impact will result from the proposed project, as conditioned, a Negative Declaration, or Mitigated Negative Declaration, will be prepared.
After the Negative Declaration (or Mitigated Negative Declaration) is completed, the proposed Use Permit will be set for a public hearing before the Board of Zoning Adjustments or the Planning Commission. A notice of the public hearing is posted at the property and sent to owners of the property within 300 feet of the site. A copy of recommended conditions and/or mitigation is sent to the applicant prior to the hearing date. All interested persons are given an opportunity to comment on the proposed Use Permit at the public hearing. If the project is approved by the Board or Commission, there is a ten (10) day appeal period for appeals to the Board of Supervisors. For approved use permits, the applicant generally has 24 months to comply with the conditions of approval and implement the Use Permit. The applicant may apply for a one year extension of time prior to the expiration of this 24 month period.

Guideline for the Preparation of Project Descriptions and Proposal
This outline is intended to provide a guideline for the preparation of Project Descriptions and Proposal Statements required for use permit applications or other land use planning permits. A thorough, detailed and quantified project description is required for a complete application and will facilitate the project review and permitting process, reduce processing timelines and help ensure a well-designed project. Project Descriptions should follow the outline below. Where a particular topic does not apply, the project description should indicate why.
This section should evaluate the constraints affecting the parcel, such as, slope, sensitive biotic habitats, creeks, easements, restrictions, proximity other sensitive land uses (i.e. schools, hospitals, residential), utilities, easements, access limitations, water availability, and septic suitability.
